# Heights (in cm) of 30 girls of Class IX are given below:

140, 140, 160, 139, 153, 153, 146, 150, 148, 150, 152, 146, 154, 150, 160, 148, 150, 148, 140, 148, 153, 138, 152, 150, 148, 138, 152, 140, 146, 148.

Prepare a frequency distribution table for this data.

**Solution:**

The __frequency distribution__ table of the given data is

Height (in cm) | Tally marks | Frequency |

138 | || | 2 |

139 | | | 1 |

140 | |||| | 4 |

146 | ||| | 3 |

148 | 6 | |

150 | 5 | |

152 | ||| | 3 |

153 | ||| | 3 |

154 | | | 1 |

160 | || | 2 |

Total | 30 |

Therefore, a frequency distribution table for this data is mentioned above.
